BACKGROUND AND PURPOSE Texture analysis is an image processing technique that can be used to extract parameters able to describe meaningful features of an image or ROI. Texture analysis based on the gray level co-occurrence matrix gives a second-order statistical description of the image or ROI. In this work, the co-occurrence matrix texture approach was used to extract information from brain M...

Genetic disorders of iron metabolism and chronic inflammation often evoke local iron accumulation. In Friedreich ataxia, decreased iron-sulphur cluster and heme formation leads to mitochondrial iron accumulation and ensuing oxidative damage that primarily affects sensory neurons, the myocardium, and endocrine glands. We assessed the possibility of reducing brain iron accumulation in Friedreich ...

Introduction: The mitochondrial defects in Friedreich ataxia (FRDA) have been reported in many researches. Friedreich ataxia is an autosomal recessive neurodegenerative disorder caused by decreased expression of the Frataxin protein. Frataxin deficiency leads to excessive free radical production and dysfunction of respiratory chain complexes. Mitochondrial DNA (mtDNA) could be considered as a c...

Friedreich ataxia is due to insufficient levels of frataxin, a mitochondrial iron chaperone that shields this metal from reactive oxygen species (ROS) and renders it bioavailable as Fe II. Frataxin participates in the synthesis of iron-sulfur clusters (ISCs), cofactors of several enzymes, including mitochondrial and cytosolic aconitase, complexes I, II and III of the respiratory chain, and ferr...

BACKGROUND AND PURPOSE Erythropoietin (EPO) has received growing attention because of its neuroregenerative properties. Preclinical and clinical evidence supports its therapeutic potential in brain conditions like stroke, multiple sclerosis, and schizophrenia. Also, in Friedreich ataxia, clinical improvement after EPO therapy was shown. The aim of this study was to assess possible therapy-assoc...

Friedreich ataxia (FRDA) is a neurodegenerative disease affecting motor and sensory systems. This study aimed to investigate the presence and perceptual consequences of auditory neuropathy (AN) in affected individuals and examine the use of personal-FM systems to ameliorate the resulting communication difficulties. Ten individuals with FRDA underwent a battery of auditory function tests and the...
